Objective To explore the strategy and outcomes of surgical treatment of thoracic ossification of ligamentum flavum(OLF),especially combined with ossification of posterior longitudinal ligament,thoracic kyphosis and epidural adhesion.Methods Fifty-three cases of thoracic OLF from January 2003 to December 2009 were reviewed retrospectively.All patients were treated by the methods of en bloc resection of semi-facet and lamina.All patients were followed up for more than half an year,including 32 males and 21 females,aged from 43 to 73 years(average 54.7 years).The lesions located in upper thoracic for 18 patients,and in thoracolumbar for 35 patients.For multi-level or jumping OLF patients,the responsible levels were determined by combination of images and clinical symptoms.For multi-level OLF with ossification of posterior longitudinal ligament(OPLL)or thoracic kyphosis(＞50°),multi-level pedicle screw fixation and correction of kyphosis were performed.For dural adhesion patients,part of cerebrospinal fluid was released with a caudal incision of dural sac resulting in collapse and epidural arachnoid separation.Ossific and adhesion dura mater were removed with integrity of arachnoid.The surgical outcomes were evaluated with preoperative and postoperative thoracic Japanese Orthopaedic Association(JOA)score,Nurick grade and neurologic functional recovery ratio.Results Fifty-three cases were followed up for 6 months to 6 years,with an average of 18 months.The average preoperative JOA score was 4.3±2.3,which significantly increased to 8.3±1.8 after operation.Postoperative neurologic functional recovery rates were 11% to 80%(average 65.8%),including excellent in 18 cases,good in 20,fair in 10,and poor in 5.The excellent or good rate was 71.7%.The mean preoperative Nurick grade was 3.7(2-5 grade)and decreased to 2.3 grade after operation.Conclusion En bloc resection of semi-facet and lamina is a safe and effective method for treatment of thoracic OLF.For the patients with OPLL or kyphosis,pedicle screws fixation and kyphosis correction was beneficial for recovery of neurologic function of thoracic OLF patients.

Objective:To explore the brain function changes in patients with cervical vertigo using functional MRI.Methods:Twenty-two patients who were diagnosed with cervical vertigo were recruited in this study for functional MRI (fMRI) analysis, while 25 age- and sex-matched adult healthy individuals were chose forhealthy controls. The Visual Analogue Scale(VAS) and Dizziness Handicap Inventory (DHI) were used to access the severity of cervical vertigo, and the six-point categorical rating scale was used to measure the frequency of vertigo. Functional MRI was used to investigate the regions with brain functional changes between the cervical vertigo group and the control group. All the data was analyzed using low-frequency oscillation amplitude (ALFF) to explore local brain function changes. The ALFF values between the two groups were tested by two independent samples t-tests. Finally, the ALFF values in abnormal brain regions were extracted using the REST software package and correlated with the diseaseduration of cervical vertigo and thevertigo scores (VAS and DHI) using Pearson correlation analysis. P <0.05 was considered statistically significant. Results:Compared to healthy controls, patients with cervical vertigo haddecreased ALFF valuesin the left superior temporal gyrus (voxel=45, t=-3.36), right superior temporal gyrus (voxel=32, t=-2.82) and left supramarginal gyrus (voxel=57, t=-4.85), and increased ALFF values in the left and right cerebellum (voxel=41, t=4.26; voxel=33, t=4.57; respectively)(AlphaSim Rest, all P values >0.05). The ALFF values of left and right superior temporal gyrus were negatively correlated with the disease duration of vertigo (left R2=0.437, right R2==0.259), the VAS score (left R2==0.453, right R2==0.341) and DHI score (left R2=0.553, right R2=0.594), respectively, and there were significant differences (all P values < 0.05). The ALFF values of left and right cerebellum were positively correlated with the disease duration of vertigo (left R2==0.555, right R2=0.490) and the VAS score (left R2=0.307, right R2=0.282) and DHI score (left R2=0.632, right R2=0.591), respectively, and the differences were significant (all P values < 0.05). Conclusion:Patients with cervical vertigo have reduced spontaneous nerve activity in bilateral Vestibular cortex, and increased spontaneous nerve activity in the bilateral cerebellum. The brain functional changes were correlated with the disease duration and the severity of vertigo.

BACKGROUNDInjectable three-dimensional (3D) scaffolds have the advantages of fluidity and moldability to fill irregular-shaped defects, simple incorporation of bioactive factors, and limited surgical invasiveness. Adipose-derived stem cells (ADSCs) are multipotent and can be differentiated toward nucleus pulposus (NP)-like cells. A hypoxic environment may be important for differentiation to NP-like cells because the intervertebral disc is an avascular tissue. Hence, we investigated the induction effects of hypoxia and an injectable 3D chitosan-alginate (C/A) gel scaffold on ADSCs.

METHODSThe C/A gel scaffold consisted of medical-grade chitosan and alginate. Gel porosity was calculated by liquid displacement method. Pore microstructure was analyzed by light and scanning electron microscopy. ADSCs were isolated and cultured by conventional methods. Passage 2 BrdU-labeled ADSCs were co-cultured with the C/A gel. ADSCs were divided into three groups (control, normoxia-induced, and hypoxia-induced groups). In the control group, cells were cultured in 10% FBS/DMEM. Hypoxia-induced and normoxia-induced groups were induced by adding transforming growth factor-β1, dexamethasone, vitamin C, sodium pyruvate, proline, bone morphogenetic protein-7, and 1% ITS-plus to the culture medium and maintaining in 2% and 20% O2, respectively. Histological and morphological changes were observed by light and electron microscopy. ADSCs were characterized by flow cytometry. Cell viability was investigated by BrdU incorporation. Proteoglycan and type II collagen were measured by safranin O staining and the Sircol method, respectively. mRNA expression of hypoxia-inducing factor-1α (HIF-1α), aggrecan, and Type II collagen was determined by reverse transcription-polymerase chain reaction.

RESULTSC/A gels had porous exterior surfaces with 80.57% porosity and 50-200 üm pore size. Flow cytometric analysis of passage 2 rabbit ADSCs showed high CD90 expression, while CD45 expression was very low. The morphology of induced ADSCs resembled that of NP cells. BrdU immunofluorescence showed that most ADSCs survived and proliferated in the C/A gel scaffold. Scanning electron microscopy showed that ADSCs grew well in the C/A gel scaffold. ADSCs in the C/A gel scaffold were positive for safranin O staining. Hypoxia-induced and normoxia-induced groups produced more proteoglycan and Type II collagen than the control group (P < 0.05). Proteoglycan and Type II collagen levels in the hypoxia-induced group were higher than those in the normoxia-induced group (P < 0.05). Compared with the control group, higher mRNA expression of HIF-1α, aggrecan, and Type II collagen was detected in hypoxia-induced and normoxiainduced groups (P < 0.05). Expression of these genes in the hypoxia-induced group was significantly higher than that in the normoxia-induced group (P < 0.05).

CONCLUSIONADSCs grow well in C/A gel scaffolds and differentiate toward NP-like cells that produce the same extracellular matrix as that of NP cells under certain induction conditions, which is promoted in a hypoxic state.

To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.
